A ball is dropped and falls with an acceleration of 9.8 m/s2 downward. It hits the ground with a velocity of 49 m/s downward. Ho
w long did it take the ball to fall to the ground?
1 answer:
Hey!
NOTE-:
u= initial velocity
v= final velocity
g= acceleration due to gravity
t= time
u= 0
v= 49 m/s
t=?
g= 9.8 m/s^2
Using first equation of motion -
v-u=at
49-0= 9.8×t
49 = 9.8t
49/9.8= t
t= 5 second
Hope it helps...!!!

Answer:
stop, drop and roll.
Explanation:
This is because rolling on the ground can help put out the fire by depriving it of oxygen.
Speed uses distance and velocity uses displacement in its calculation.
For 100 m race, distance = displacement. Hence speed = velocity
For 400m race, distance ≠ displacement. distance = 400m whereas displacement = 0m. Hence speed ≠ velocity
Answer:
the acceleration of the car is -4.9m/s2.
the direction is opposite to the actual direction, since the acceleration is negative.
